Mike you nailed it. Fast for me only has one meaning since I design soeakers. How fast do the drivers start and stop. View attachment 68377
They say the human ear can start to detect audible differences around 5 ms. I believe this is false but we don't have a way to prove it. The above step response shows a soeaker that starts and stops within roughly 2ms. It returns to base line. Find me another box soeaker that can do this. Most box soeakers don't return to baseline until many ms well into the auditory range . This is distortion. The only other soeakers I have seen return to baseline this fast are planners. I can see why someone made the comment that fast means lean because you are removing so much hangtime from the woofers. Fast should not mean lean. I have never considered my soeakers lean and it is the exact opposite. For me soeed is everything. A slow soeaker would be a very forgiving soeaker but you IMO will never capture the realism of the performance.
Nah I nailed it before Mike Though I guess I didn't talk about rise times.
Is that from a ceramic driver?
